ABC's Miss Fisher's Murder Mysteries set to become an action movie trilogy

Australian television's most loved private detective could become an Indiana Jones-style action hero on the big screen if producers behind Miss Fisher's Murder Mysteries can pull it off.

The team behind the hit ABC series are currently penning scripts for a movie trilogy based on Essie Davis's glamorous detective character Phyrne Fisher, with meetings in Los Angeles scheduled for early next year.

In an interview with News Corp AustraliaMiss Fisher's Murder Mysteries producers Fiona Eagger and Deb Cox said they wanted to expand the series which has become a worldwide hit since premiering on the ABC in 2012.

The series which revolves around the personal and professional life of Phryne Fisher, a private detective in 1920s Melbourne, has been broadcast in 120 countries and bought by Netflix.

"I reckon we could do three Miss Fisher movies, absolutely," Eagger said. "The fan base is so passionate. If you've got a successful franchise, why not (make more than one movie)?"

"We want it to be like the Indiana Jones movies," Eagger added. "We might not have Steven Spielberg's budget but that is what she (Phryne Fisher) is - an action hero. She got to be able to fly the world.

"It could be 'Miss Fisher and the Crypt of Tears' so she has to go to Arabia. We'd love to go to India. We have fun thinking about the destinations."

Based on author Kerry Greenwood's mystery novels, the series won an AACTA Award in 2014 and has seen Essie Davis nominated for the Gold Logie twice.

Despite a huge ratings run, a fourth season is on ice after Davis landed a role on HBO sensation Game of Thrones and moved to London.

Securing Davis for the trilogy would be imperative but Eagger and Cox are confident they can fit around her schedule.

"Essie is in London at the moment and a feature film can fit into her schedule easier than a five-month ongoing TV series so the aim is in the second half of next year to be able to begin filming," Eagger said.

For fans mourning the end of the series, the pair are also planning a Miss Fisher spin-off series which would air on the ABC with a new star.

Focusing on a younger, 18-year-old Fisher, the spin-off would follow the aristocrat character as she migrates from the UK to Melbourne and stumbles into her detective work.

In an interview with Fairfax Media last year, Davis said her career trajectory was beyond anything she'd imagined.

"I'm still heading towards the top of Mount Everest," she said, "and my goals are way beyond what I've achieved."
